ABSTRACT

An uninterruptible power supply (UPS) socket of the present invention consists of a front panel, an upper cover, a socket member, a wiring insulation plate, a battery set, a print circuit board assembly, a detachable lower cover, a power cord lead and several components. The upper and lower covers are connected via several electric conductive wires, and said print circuit board assembly contains a power circuit board, a control circuit board and a surge protection circuit board.

FIELD OF THE INVENTION

The present invention relates to an uninterruptible power supply (UPS) device, and more specifically to an uninterruptible power supply socket capable of adapting a 6 volt battery.

BACKGROUND OF THE INVENTION

Conventional UPS devices use 12 volt batteries as main power supply to cope with large power consumption required by ICs especially circuits of switching power supply and circuits of inverters. Due to this large power consumption, the sizes of transformers, ICs and other components of conventional UPS devices are large; and therefore, conventional UPS devices have notable drawbacks such as high cost, difficult maintenance and not being portable.

SUMMARY OF THE PRESENT INVENTION

The UPS socket of the present invention uses a central processor unit (CPU) and a rechargeable circuit for boosting its power efficiency, and therefore is capable of solving the drawbacks associated with the prior art mentioned above.

A feature of the UPS socket of the present invention is to use a 6 volt battery to provide the power supply for the equipment during the interruption of consumer electricity comprising a power circuit board, a control circuit board and a surge protection circuit board.

Another feature of the present invention is that the size of its configuration is similar to commercial extension sockets, and its size is much smaller than conventional UPS, yet capable of providing 3 sets of surge protection receptacles and 3 sets of UPS receptacle on the surface panel of the UPS socket. When electricity is interrupted, the function of CPU controls may automatically save the application and data and then close the program to reduce power consumption. If electricity is not restored within a few minutes and there is no substitute emergency power available, the CPU will automatically shut down the operating system of the computer to avoid losing data in the process.

Another feature of the present invention is its compact modular construction capable of saving assembly and maintenance time cost and improve quality of the UPS socket.

In a preferred embodiment of the present invention, the construction members is comprising of a face panel, an upper cover, a socket member, a wiring insulation plate, a battery set, a print circuit board assembly, a detachable lower cover, a power cord lead and several components, wherein said upper and lower covers are connected via several electric conductive wires.

The UPS socket of the present invention in general contains a print circuit board assembly consisting of a power circuit board, a control circuit board and a surge protection circuit board, wherein said power circuit board includes an AC/DC rectifier, a DC/DC inverter, a switch controller, a rechargeable charger, a DC/DC direct current bus booster, an output inverter and a computer transmission interface circuit. In addition, said control circuit board includes a monitor, a charge controller, a DC/DC controller, an output inverter driver and a CPU; and said surge protector includes a set of surge suppression circuits.

These and other features and advantages of the various aspects of the present invention will become more apparent upon reading the following description of a preferred exemplified embodiment of the present invention and upon reference to the accompanying drawings.
